WILLIAM S. MAYO, OF NEW YORK, N. Y.

OVERFLOW FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 430,966, dated June 24;, 1890.

Application filed January 25, 1890.

To all whom it may concern.-

Be it known that I, VV'ILLIAM S. MAYO, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Overflows for ater-Closets and other He ceptacles, of which the following is a specification.

This invention relates to overflows for water-closets, wash-basins, wash-tubs, and the like; .and the invention consists in the details of construction set forth in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 is a sectional view of a water- .closet bowl with my invention. Fig. 2 is a sectional view of a wash-basin with my invention, the section being taken along a; 00, Fig. 3. Fig. 3 is a plan view of Fig. 2. Fig. 4. is a perspective view of a faucet. Fig. 5 is a section along y y, Fig. 4.. Fig. 6 is a section along .2 2, Fig. 5.

In the drawings, the letter A indicates a bowl, basin, or receptacle having overflowopenings B, through which the overflow-water can pass olf. The overflow-water passes into a cup E. This cup is preferably secured to the outside of the receptacle A; but I do not confine myself to this particulararrangement of the cup. The overflow-water passing from the cup E flows through the tube F into the outlet H, which outlet can also serve for takin g off the water from the receptacle A. The tube F has a bend or trap G, which keeps a certain supply of water standing in the cup E, so as to prevent foul gases passingthrough the tube F and out at the openings B;

In Fig. 1 a jet or inlet I is shown leading into the cup E, and when fresh water is supplied to the receptacle A part of said fresh water passes through the inlet I into the cup E, thereby cleansing said cup and keeping the water-supply of said cup fresh and pure.

The inlet or jet I may be variously formed. In Fig. 1 said inlet is a passage leading from the fiushing-rim of the receptacle A into the cup E. In Figs. 2 to 6 theinletI is a branch or jet connected with the faucet K. WVhen said faucet is moved to its open position to fill the receptacle A, the inlet or jet I is temporarily opened, so as to supply a certain amount of fresh water to the cup E. By means of this Serial Na. 338,076. (No model.)

inlet or jet I the trap G is kept sealed with fresh water, so as to prevent foul odor or the escape of foul gas from the overflow-pipe. If through long non usage the Water in the cup E is evaporated, the valve or ball L sinks to the bottom or onto the outlet of said cup and closes said cup against the entry of foul gas. When water is in the cup, said ball L floats in the cup, so as to leave any excess of water in the cup free to flow off. The ball L is shown provided with a weight Osuch as a drop of mercury, a supply of shot, or the like-which weight presses the ball L firmly into place when said ball is required to close or seal the cup E. When the receptacle A is being emptied, the rush of water through the outlet I1 might cause emptying or siphonage of the trap G and cup E. To prevent such emptying or siphonage, I provide the tube F with an enlargement or air-cl1amberP,which I have found will prevent the formation of a vacuum to such an extent that the trap G" will not be emptied or siphoned out.

The water-closet bowl A in Fig. 1 is shown provided with a stopper 0, connected to the cover (not shown) by a link D, and with a valve N, having the links M R, as described in my United States Patent No. 418,580, of December 31, 1889. hen the water-closet is not in use, the'valve N rests against the tube F and prevents foul gas passing from the outlet H into the tube F. When the water-closet is in use, the valve N is temporarily moved to the position shown in broken lines in Fig. 1, leaving the tube F temporarily open. As the valve N hangs loosely against the tube F all the time the water-closet is not in use, said valve does not prevent escape of water from the tube F in case of an overflow, while at the same time said valve N prevents foul gas entering the tube F, and thus both ends of the overflow are hermetically sealed, even in case the water in the cup or trap is evaporated because of long non-usage.

My invention is applicable in various places besides water-closets or wash-basinsas, for example, in bath-tubs, wash-tubs, and other receptacles.

WVhat I claim as new, and desire to secure by Letters Patent, is-=- 1. As a new article of manufacture, an overflow-trap for bowls or receptacles constructed to maintain a body of water, in combination with a jet I, made to supply fresh water to the upper part of the trap every time the receptacle is beingused, substantially as described.

2. The combination, with a bowl or receptacle having an overflow-opening and a bottom outlet, of a cup'arranged to receive the overflow-water, a tube leading from the cup, having a trap-bend and connected with the bottom outlet of the bowl or receptacle, a ball or float valve located in the cup to close the trap-tube, a valve for closing the end of the trap-tube which connects with the bottom outlet, and a jet for supplying fresh water to the cup whenever the bowl or recepta- 01c is used, substantially as described.

3. As a new article of manufacture, an over flow-trap for bowls or receptacles constructed to maintain a body of water, in combination with a jet 1, made to supply fresh water to the upper part of the trap every time the bowl or witnesses. H 7
